概览

Olodaterol is a long-acting beta2-adrenergic agonist used in the management of chronic obstructive pulmonary disease (COPD), including chronic bronchitis and/or emphysema.

作用机制

Olodaterol is a long-acting beta2-adrenergic agonist (LABA) that exerts its pharmacological effect by binding and activating beta2-adrenergic receptors located primarily in the lungs. Beta2-adrenergic receptors are membrane-bound receptors that are normally activated by endogenous epinephrine whose signalling, via a downstream L-type calcium channel interaction, mediates smooth muscle relaxation and bronchodilation. Activation of the receptor stimulates an associated G protein which then activates adenylate cyclase, catalyzing the formation of cyclic adenosine monophosphate (cAMP) and protein kinase A (PKA). Elevation of these two molecules induces bronchodilation by relaxation of airway smooth muscles.

适应症

Olodaterol is indicated for use in chronic obstructive pulmonary disease (COPD), including chronic bronchitis and/or emphysema. It is not indicated for the treatment of acute exacerbations of COPD or for the treatment of asthma.
